Alternative Fuel Paper
Alternative fuels are made to help support our environment and to reduce the amount of harm we are causing. Biodiesel is a renewable fuel made from vegetable oil, animal fats or recycled restaurant grease. Biodiesel is similar to petroleum diesel but it is a cleaner-burning alternative and can reduce emissions. Biodiesel is produced in the United States and used in diesel engines. Since it is made in the United States, it aids in helping us reduce our trade and dependence on other countries when it comes to oil.
Biodiesel produces a better air quality which is great for our environment and decrease car pollution. The nitrogen oxide levels are near zero and these engines are one of the cleanest engines on the road. This alternative fuel decreases greenhouse gas emissions. Its carbon dioxide emissions are 75% lower than those of petroleum diesel! (Advantages and Disadvantages of Hydrogen Energy) It also improves fuel lubricity which is better for the engines. Diesel engines depend on this because it keeps the parts from wearing down quickly. Biodiesel is a lot safer than petroleum diesel if spilled and enter the environment. It is less combustible than the petroleum diesel and is safer to handle, store and transport.
Although there are some great advantages, there are some bad disadvantages. Biodiesel is about one and a half times more expensive than petroleum diesel. It can also cause harm to rubber hoses in the engines. Although it creates a cleaner engine, all the dirt can collect in the filter and clog it. Therefore, the filters have to be changed after the first few hours of use.
Another fuel alternative is hydrogen which produces a nerd-zero greenhouse gas emissions. It only emits water vapor and warm air which does not harm our already much polluted environment. Hydrogen when put in a fuel-cell, it is emission-free and can be made from various domestic energy sources. Resources such as solar energy, wind, coal, natural gases...
